Each native hole-nesting bee and beneficial wasp needs a nesting hole that is the right size for their species. Our nesting materials are offered in the size range that native bees prefer.

We design our nesting holes to be easily opened to identify the bees and wasps nesting in your NBN habitat. We do not recommend using drilled blocks of wood or bamboo because they are impossible to open and can contribute to mold, pest and disease build up.
